Adds the continuation plan for SP21 T2.2 Phase 1.5 (entry_q tracking
in portfolio_state slot 6) + Phase 2 (wire enrichment to real
per-trade tape from gpu_backtest_evaluator). Self-contained plan
that a fresh session can pick up cold:
- State-at-session-start summary with all 8 prior commits
- Phase 1.5 design (storage slot, capture site, plumbing,
EvalTrade extension)
- Phase 2 design (training_loop wire-up, enrichment refactor,
E5 alternate-signal options with recommendation)
- Hard rules carried from prior session (no NULLs, no stubs,
atomic per feedback_no_partial_refactor)
- Verification plan (5 GPU oracle test suites)
- Open design question (E5 alternate signal) with recommendation
- Multi-phase continuation map (Phases 3-7 + Phase 8)
- Final cascade verification (smoke run criteria)
Also amends the parent SP21 plan
(2026-05-10-sp21-train-eval-coherence-isv-defrost.md) with the
T2.2 multi-phase scope section that documents the full per-trade-tape
expansion the user committed to (option 3 — full wiring across
multiple sessions instead of the original recommended option (b)
aggregate-stats refactor).
